2  我低uboot里面配置

#define CONFIG_BOOTCOMMAND   "sf probe 0; "                           \
                             "sf read 0x41800000 0x100000 0x10000; "  \
                             "sf read 0x41000000 0x110000 0x400000; " \
                             "bootz 0x41000000 - 0x41800000"

#define CONFIG_BOOTARGS      "console=ttyS0,115200 earlyprintk panic=5 rootwait " \
                             "mtdparts=spi32766.0:1M(uboot)ro,64k(dtb)ro,4M(kernel)ro,-(rootfs) root=31:03 rw rootfstype=jffs2 vt.global_cursor_default=0"

#include <configs/sunxi-common.h>

同时在Linux里面dtsi里面的chosen加了下面的
simplefb_lcd: framebuffer@0 {
                        compatible = "allwinner,simple-framebuffer",
                                     "simple-framebuffer";
                        allwinner,pipeline = "de0-lcd0";
                        clocks = <&ccu CLK_BUS_TCON0>, <&display_clocks 0>,
                                 <&display_clocks 6>, <&ccu CLK_TCON0>;
                        status = "disabled";
                };
在pio里面加了如下
lcd_rgb666_pins_a: lcd-rgb666-pe {
                                pins = "PE0", "PE1", "PE2", "PE3", "PE4", "PE5",
                                       "PE6", "PE7", "PE8", "PE9", "PE10", "PE11",
                                       "PE12", "PE13", "PE14", "PE15", "PE16", "PE17",
                                       "PE18", "PE19", "PE23", "PE24";
                                function = "lcd0";
                        };

但是目前来设备树里面没有看到有fb0类似的设备的
